One further famous example was the so-called “fiddle brake”, given its name much later by Ferrari technical boss Ross Brawn, but known within the team as “brake-steer,” that McLaren ran in the latter half of 1997 and into 1998. This simple concept allowed the rear brakes to operate on either the left or right side only, providing a clear benefit under acceleration in corners – and an instant lap time advantage.

11.1 Brake circuits and pressure distribution
11.1.1 ... all cars must be equipped with only one brake system. This system must comprise solely of two separate hydraulic circuits operated by one pedal, one circuit operating on the two front wheels and the other on the two rear wheels. ...
11.1.2 The brake system must be designed so that within each circuit, the forces applied to the brake pads are the same magnitude and act as opposing pairs on a given brake disc.

Basically a standard diff using brakes to shape power output. Basically a brake limited version of a limited slip diff.
This doesn't really seem like that big of a disadvantage to me. You can just keep increasing downforce until the tires are able to give you the traction you need for any maneuver. It seems like that should scale as far as you need it to, and be way more efficient than rockets. I guess the limits would be in the tires and suspension.
You would need something other than pneumatic tires, or some sort of dynamic tire pressure system.
Thrust vectoring could serve as a safety system to dynamically produce downforce in case a high speed car starts to go airborne, can counter spin-outs, etc.
